  • Eos is a newly discovered molecular cloud sitting just 94 pc from the Sun. It was detected through the far-UV emission of its molecular hydrogen, having been missed in conventional molecular gas surveys due to a low abundance of common gas tracers.

  • Classical novae are thousands of times brighter than dwarf novae, and are accompanied by the formation of shells around the system. This paper reports the discovery of a shell an order of magnitude more extended than those detected around many other classical novae surrounding the prototypical dwarf nova Z Camelopardalis, thereby observationally linking the objects.

  • The Leo ring is a massive, 200-kpc-wide structure orbiting the galaxies M105 and NGC3384 with a 4-Gyr period. This paper reports ultraviolet light originating from gaseous substructures, which is attributed to recent massive star formation. If structures like the Leo ring were common in the early Universe, they may have produced a large, yet undetected population of faint, metal-poor, halo-lacking dwarf galaxies.

  • Mira is one of a class of low-to-intermediate mass stars in the late stages of stellar evolution. This paper reports the discovery of an ultraviolet-emitting bow shock and turbulent wake extending over 2 degrees on the sky, arising from Mira's large space velocity and the interaction between its wind and the interstellar medium. This wind wake is a tracer of the last 30,000 years of Mira's mass-loss history.

  • The amplitude and sinusoid-like shape of the optical variability of the light curve of PG 1302-102 is best fitted by relativistic Doppler boosting of emission from a compact, steadily accreting, unequal-mass binary, which is consistent with archival ultraviolet data, and suggests the existence of a binary black hole in the relativistic regime.
